LEGEND GT HELP!

[Mr Brightside]

Hi guys I may have posted this a while back one of our units is the legend gt. I have replaced many of the parts over the years and honestly this little machine cleans carpet great! The problem is my techs struggle with tile and grout cleaning with the machine it seems to lack FLOW. I have replaced one of the heat exchangers... I have descaled and descaled and descaled... I have replaced the bypass valve and bought a brand new spinner.... All in all nothing helps.

I have a water otter that I have tested against the machine and the water otter puts out more water faster with better pressure.

what would you do the van goes out everyday and I am thinking about scraping it and starting over!

I'd flow test the pump.

If it's doing all it's designed for then you need may want to use the otter for your tile jobs.

ok ill ask my repair guy to do a flow test if flow is low do you know what they do to improve or fix it?

How old is the pump? Has it been rebuilt before?

You also need to check the pump pulley size. It may have been geared for a certain speed and for more flow, it may need to run faster.

Make sure the belt is tight and in good order. If it's slipping that will affect the performance.

 

[Mr Brightside]

ok thanks guys ill check when the last time we rebuilt the pump... I believe I overhauled it when I put a new engine in...

a smaller pump pulley will make it turn faster, flowing more.

 

[Mr Brightside]

ok I talked to my mechanic and he said the heat exchangers could not handle more pressure but I would like to do the pulley for sure!

What are the negatives for upgrading the pulley? As far as flow goes for carpet wouldn't the size jets on our wand control the flow to be the same?

When I looked at the pump specs, it seems most are capable of going up to 3000 psi. My Boxxer pump can do 3000 psi at 4.5 GPM but limited to 1000 psi only. The issue is the plumbing systems. They are built with specific psi to operate, otherwise, you would risk damaging the plumbing systems.

The pump has to spin at the proper rpm to get its maximum flow. The jets on the wand control how much of that maximum flow you are using. If you are using the general pump that I see on the new machines, it should be around 1200 psi and 3.5 GPM.

If you have descaled several times, you might take the q connect off at the front panel and flush the system. You could have a build up behind the q connect.

I am gonna try that
